I couldn't figure out what the forked end was for - obviously not for removing basting. I eventually found out that it was a magnetic end meant to pick up a nail from a rounded head so the end of the nail is pointing down where it will be. A light tap sets the pin in place, then the hammer is turned to drive it fully into the frame. The old hands stuffed nails in their mouths and pulled them out one by one with a magnetic end. I don't think I will.
